UNSPSC 51201801: Bacterial immunoglobulins

This classification denotes bacterial antibodies.

UNSPSC 51201801 Bacterial immunoglobulins is a Commodity code under which state and local governments procure vaccines and immunological products for public health programs. The recent activity under this code reflects procurement of specific vaccines for disease prevention and control by state health agencies. The Mississippi State Department of Health posted a sole source notice on July 13, 2026 for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with an objection deadline of August 3, 2026. State health departments represent the primary issuing body under this code, purchasing vaccines and immunological preparations to support disease surveillance, prevention, and immunization programs at the state level.

The geographic spread of recent activity under this code is limited; the single documented recent opportunity originates from Mississippi. The Mississippi State Department of Health's notice was a sole source procurement rather than a competitive RFP or IFB, meaning the agency asserted that only one vendor could supply the required vaccine. The procurement process allows objections to the sole source designation if alternative suppliers can demonstrate capability to supply the commodity; objections must be submitted in writing to Cynthia Brasher at the Mississippi State Department of Health Purchasing Department by August 3, 2026 at 10:00 a.m. CST. The notice does not disclose quantity, contract term, or estimated value. Firms pursuing opportunities under this code should monitor state health department procurement channels and be prepared to respond to sole source challenges or, if the sole source designation is withdrawn, to competitive solicitations.
